If I do a readline loop I always do: while (defined ($line = <$file>)) Is there something magical happening here I don't know about? I know about the magical: while (<$file>) which is equivalent to: while (defined($_ = <$file>)) but I don't know of any magic in the while loop at the top.
Whether you use: while ( <FH> ) Or: while ( my $line = <FH> ) The condition is always tested for undefinedness.
